Someone here argues there is no incentive to provide liquidity:
My gut disagrees but I'm having difficulty formulating the paradigm under which an entity is incentivized (economically) to provide liquidity.
What would this business case look like? There is a technological costs of hardware/network resourcess to be sufficiently connected and capable of servicing many (hundreds or thousands ) channels. At some point you need to collect relay fees to cover those costs and beyond that generate profit. (for a sustainable business model)
What does this look like, whats the break even? How to prove it?
